.isWithin(tolerance)
  .of(other.getPressure());
check("getSize()").that(actual().getSize()).isWithin(tolerance).of(other.getSize());
check("getTouchMajor()")
  .that(actual().getTouchMajor())
   .isWithin(tolerance)
   .of(other.getPressure(i));
 check("getSize(%s)", i).that(actual().getSize(i)).isWithin(tolerance).of(other.getSize(i));
 check("getTouchMajor(%s)", i)
   .that(actual().getTouchMajor(i))

@Override
public boolean onTouchEvent(MotionEvent event) {
  int largestIndex, largestSize=0; //holds largest point data
  for(int i=0; i<event.getPointerCount(); i++){ //loop through each touch point
    if(event.getSize(i) > largestSize){ //if this size is greater than the previous largest one
      //store the new size and pointer index
      largestSize = event.getSize(i);
      largestIndex = i;
    }
  }

  //work with the largest touch point here

  //you can change this to return true if you're always handling the touchevent completly yourself
  return super.onTouchEvent(event);
}
